The ACT-1 connects to one of up to eight amplifiers on a channel. Multiple ACT-1s
are required for amplifiers on multiple channels.
To install an ACT-1, follow these steps:
1. Connect the low-level audio circuit to the terminal block on the ACT-1.
2. Connect the ACT-1 to the first amplifier in the chain.

Step Action
1 Using the supplied cable, connect the Earth ground terminal on each ACT-1 to P8 on the AA-100/
AA-120 or to a screw on the upper left corner of the AA-30. The COMN terminal is intended for
optional shielding of the secondary side of the ACT-1 (low-level audio from the ACT-1 through
each amplifier). To use shield, connect to the common of the local power supply—but do not
connect this shield to the shield from the primary side of the ACT-1.
2 Daisy-chain the secondary side of the ACT-1 (low-level audio) up to a maximum of eight
amplifiers.
3 Draw additional low level audio risers (isolated from the main riser) from P4 on an audio amplifier.
